  • Publication number: 20100304635
    Abstract: This is the recreational flying ring of U.S. Pat. No. 4,669,996 having material improvements added and made primarily to mitigate the premature curving of the flight path as the ring inherently slows in forward speed at a faster rate than rotational velocity during the flight. The improved performance of the flying ring may permit it to be used on a Disc Golf Course or as a fun toy for young people if molded in soft integral skin foam.

  • Patent number: 4669996
    Abstract: A recreational spinning ring includes a primary and secondary airfoil. The primary airfoil is located on the bottom of the ring near the outside rim and provides a downward force while it is in flight. An upward force is provided by the secondary airfoil located on the top surface of the ring closer to the inside edge. The downward force of the primary airfoil counterbalances the excess lift provided by the secondary airfoil so that sufficient net lift remains to keep the ring airborn. The improved flying ring has the ability to fly in an exceptionally straight path over intermediate and long range distances.
